Impact of carbon pricing on distributed energy systems planning
Abstract. Carbon pricing is being implemented by several governments to curb CO 2 emissions. This work studies its impact on distributed energy systems design which are powered by both renewable and fossil fuels. In particular, the analyses investigate a real case study situated in Singapore, characterized by cooling and electricity demands.
Unlocking the Potential of Distributed Energy Resources
Distributed energy resources (DERs) are small-scale energy resources usually situated near sites of electricity use, such as rooftop solar panels and battery storage. Their rapid expansion is transforming not only the way electricity is generated, but also how it is traded, delivered and consumed. Accordingly, DERs can create new power …
